Specicatiou of Letters Patent.

Application led February 13, 1905. Serial No. M7352.

To all 'whom 'it may concern;

Be it known that T, FRED S. Morrow, a subject oit the King ot Great Britain, residing at ll'orcester, in the county ot llTorcester and State of Massachusetts, have invented a new and useful 1Wheel or Roller, oit which the following is a specication.

This invention relates -to a wheel or a roller tormed ot sheet metal. i

. The principal objects of the invention are to provide a strong and durahle construction of such character that the parts vcan he stamped out ot relatively small nuinher ot pieces ot sheet metal in an inexpensive manner and can be lixed in their tinal position with` respect to each other in a simple, inenpensive. and hrm manner; also to provide certain improvements in details ot construction as will appear' hereinafter.

Reference is to` he had ing drawings in which,

Figure l is a side elevation ot a. practicable forni ot the invention, Fig. 2 is an end view thereof, Fig. 3 is a longitudinal sectional view, F ig. l is an end `i-'iew ot the same showing the parts disassembled, and sectional Views showing two steps in the manufacture of the article. The invention is shown embodied in a forni suitable for small wheels or rollers and having a shaft `or stud l0, with two raceways ll, tor the hearing halls l2. Uutside of this is a hall race 13, shown as consisting of two pieces oi sheet metal having ahutting Hanges il extending outwardly and in con tact with each other so as to ltorm a huh. These two parts are not directly secured together hut are intended to he held in a proper' position hy the other parts ont the wheel.

The rim or tread l5,

ot the wheel is provided with an interal inwardly extending -rond the center, so as to torni a side wall t6. i tits inner end this has an inwardlyr en tending projection l?, forming a shoulder against which one ot the hanges ll rests. Tn the condition oi this part ot the wall lh shown in Fig. 5, there is a cylindrical passage 18 extending outwardly troni the projection 17, to permit the hall race tohe inserted to assume the position shown in lFig. h. The ball race is held in position hy in'- troducing a punch a into the cupped out portion ot' the wall i6 as indicated to the acconipanyf in lTig. 6

and upsetting a part ot the metal thereof to forni .an annular projection 19, tor engaging Harige lei, oit the lett hand part ot the hall race. This permanently secures the hall race in position. Tt is to he observed that the edge or wall 16 is integral with the tread or rini l and tormed therewith in one series ot operations as shown4 in l?" 5.

The other side wall oit the wheel is tortured hy a circular plate 20 haring an inwardly projecting portion 2l provided with a central circular 'pertoration for receiving the shoulder ot the ball race. Tn order to insert the plate 20, a punch h is torced into the open end oit the rim oit the wheel so as to i'orni an inwardly extending shoulder 23 against which the edge oit the plate 2U can rest. This plate is then put into position with its outer edge against the shoulder 23,

and its inner edge against the projection l'l' and the shoulder ot the hall race. Another punch is introduced rim at 2l, to cover the edge oit the plate 20, and this securely holds the latter in position, and as its inner circular. edge ahuts against the projection It? and the cylindrical surllace ot the hall race or huh it will he seen that what was originally the open edge ot the rim is tirnily supported. g During these punching operations the hlank is held in dies as is well understood in this art.

Tt will he seen that hy means of this construction a rery simple, strong and durable roller or wheel is ohtained that can he manufactured in an inexpensive manner, and thatconsists ot only iour parts.,

While T hare illustrated and descrihed one embodimentot the invention, T am aware that many nlodihcations can he niade therein, hy any person skilled in the art without departing from the scope ot the invention as expressed in the claims. Therefore, T do not wish to he limited to all the teatures oit construction or steps ot manufacture shown and described, hutA what T do claim is l. is an article oit manutacture, a wheel or roller haring a rim or tread, an integral 'wall extending inwardly trom one edge thereol and suhstantially acro' the wheel or roller to a point near the opposite side, a hall race held hy said integral wall, and a wall connected with the tree edge ol the rim or tread and with `the inner portion ot the integral wall. v

2. ils an article oit manutacture, a wheel to upset the edge ot the llt) -an integral inwardly extending wall on one or roller co iprising a rim or tread having 3. As an article of manufacture, a wheel l ,or roller comprising a rim or tread having j an integral inwardly extending wall on one E side provided with an inner annular groove i at its inner edge, a ball race having a cirl cular flange held in said groove, and a plate abutting atits inner edge against the inner edge of the integral wall and the surface of the ball race, and fixed atits outer edge to the rim or tread.

4. As an article of manufacture, a wheel or roller having a rim or tread, a wall extending inwardly therefrom, and a ball race or hub, said Wall having an inwardly extending edge and said ball race having a projection resting against said edge.y said wall -being upset on the other Side of the projection to hold it in place.

5. A wheel or roller comprising a rim or tread having an integral inwardly extending wall on one side, a separatewall on the other side, said rim having an annular groove for receiving the outer edge of the l separate wall and the inner edge of the separate wall abutting against the inner portion i of said integral wall, said integral Wall having an annular groove, and a ball race or hub in two parts projecting into said groove.

6. A wheel or roller comprising a rim or tread having an integral inwardly extending wall having an inner annular groove, and a ball race or hub in two parts projecting into said groove and held thereby. i

'i'. As an article of manufacture, a wheel or roller having a rim or tread, and provided with awall integral with the rim or tread, another wall separate therefrom, and a ballrace or hub connected with said walls, said rim or tread having a groove in its edge to secure the edge of the separate Wall.

8. As an article of manufacture, a wheel or roller having a rim or tread, a fixed wall extending inwardly therefrom on one Side, a ball race held by said fixed wall, and a plate on the other side abutting againstthe outside of the ball race and connected with the edge of the rim or tread.

ln testimony whereof I have hereunto set my hand, in the presence of two subscribing witnesses.

FRED `S. MORTON.
